sdow is not able to follow links with accented characters

[Francesco Giordano]

Apparently links with accented characters will break the search result, for tags it's working fine, the problem is that unicode chars are not handled correctly

Nope, there actually is no path between those pages because no pages link to École:

sqlite> SELECT id FROM pages WHERE title = "École";
19771211
sqlite> SELECT incoming_links FROM links WHERE id = 19771211;

École is a disambiguation page and there is a general Wikipedia policy to never link to a disambiguation page. I've kept them around for completeness, although I've definitely considered removing them.

To prove that unicode characters work properly, try doing Doppelgänger to El Niño.
